# LanguageType

Restrict to natural-language or programming-language tagged activity. Sourced from a sampled, upsampled dataset, so `total_tokens` is an estimate and is aggregated weekly (the trailing weekly bucket may include traffic past `end_date`). Cannot be combined with `modality`, `context_bucket`, or `category`.

## Example Usage

```python theme={null}
from openrouter.operations import LanguageType

# Open enum: unrecognized values are captured as UnrecognizedStr
value: LanguageType = "natural"
```

## Values

This is an open enum. Unrecognized values will not fail type checks.

* `"natural"`
* `"programming"`
